Abstract: The spillway for Kaw Dam, which is expected to be subjected to discharges as large as 616,200 cfs, was studied on a 1:100-scale comprehensive model to determine flow conditions in the approach and exit channels and the performance of various elements of the structure. Modifications to the left abutment were recommended to provide a more economical design without inducing excessive turbulence, surging, and/or drawdown in the gate bays adjacent to the left abutment. The capacity of the spillway as determined with the model was slightly less than computed. Modification of the left abutment did not alter the capacity. Tests indicated that the original design stilling basin performed satisfactorily. However, in order to conform to the foundation, the basin was sloped laterally from left to right and the model indicated that this modification did not adversely affect stilling basin performance. Tests also indicated that use of a dike to prevent return flow from the large expanse left of the exit channel and stilling basin would permit reducing the height and length of the left training wall and prevent excessive scour along the left portion of the exit channel. The designs of the right stilling basin training wall and the right tailrace training wall also were developed with the model.
